D 1/2 Rd Capacity Improvement Project

The D 1/2 Road Capacity Improvement project is a large‑scale civil construction effort in Grand Junction, Colorado, aimed at upgrading storm‑drain, culvert, and irrigation infrastructure while adding new pavement, sidewalks, and related site work. Five local contractors were each awarded a portion of the roughly $24 million contract, competing on unit‑price items covering pipe installation, manhole construction, concrete work, asphalt paving, erosion control, fencing, and utility relocation. The solicitation was an Invitation for Bids, with six addenda issued and all bidders meeting pre‑qualification criteria. • Scope includes installation of RCP and PVC storm‑drain pipes (18‑48 in.), multiple manhole types, and irrigation piping. • Additional work covers concrete curbs, sidewalks, hot‑mix asphalt, trench de‑watering, erosion control, fencing, signage, and site grading. • Competitive unit‑price bidding resulted in a total awarded value of about $24 million split among five Grand Junction firms.
